Wearable Computing: In ubiquitous computing a user has access to many computing devices. These computing devices will be unobtrusive and provide seamless access to a wide variety of data and allow the user to perform tasks as needed, where needed. The objective of ubiquitous computing is to move interaction with computers out of a person’s central focus and into the user’s peripheral attention where they can be used subconsciously. Ubiquitous computing is often characterized by the attributes of mobility, inter-connectivity and context-awareness. One of the key attributes of ubiquitous computing is mobility. An individual will carry or wear multiple devices and move about the office, home or public places. It's obvious that these devices should be both easily transportable and simple to interact with. User interfaces, whether voice, pen based or key based, will present particular challenges in mobile devices. Frugality will be important when mobile devices are designed since resources of mobile devices are minimal. Displays of mobile devices have limited graphics capabilities and are quite small. Similarly, memory is limited, disks may be nonexistent, and software availability may be restricted.

Virtual Reality: Virtual Reality (VR), also known as 'artificial reality', 'artificial worlds', 'virtual worlds', 'virtualities', is a fully-immersive, absorbing, interactive experience of an alternate reality through the use of a computer structure in which a person perceives a synthetic (i.e., simulated) environment by means of special human-computer interface equipment and interacts with simulated objects in that environment as if they were real. Several persons can see one another and interact in a shared synthetic environment.

Neural Interface: A neural interface allows human brain communicate directly with a computer, without any other equipment. That kind of interface allows any illusions to be inputted to human nervous system. Thus you don't need any virtual glasses or data-gloves for accessing the cyberspace.

Artificial Intelligence: A self aware mathematical construct, an Artificial Intelligence (or AI) is a truly intelligent computer program with its own thoughts and ideals. It may even possess emotional simulation but this is usually reserved for those AI's who have to integrate with humanity. An AI is a heuristic program. It can learn from its experiences and thus may improve its skill levels or even learn new skills. It can access chip skills to enhance its abilities. Such chips must be accessible for this to happen. An AI can forget skills as a result of taking damage to its program volume. AI are also capable of moving in and out of any electronic/computer based system. This includes an android mind. Many self-aware androids are actually AI that are uploaded into an android body.

Virtual Intelligence: The scaled down version of a partial AI, aka the fragment AI. VI can interact with living things like an AI can but only with what it is programmed to do. It doesn't think for itself like an AI does. Essentially an AI which is not self-aware and therefore does not have free will. This is one of the many things it can be used for.

Nanotechnology: Nanotechnology is an anticipated manufacturing technology giving thorough, inexpensive control of the structure of matter. The term has sometimes been used to refer to any technique able to work at a sub-micron scale; Molecular nanotechnology means basically "A place for every atom and every atom in its place." (other terms, such as molecular engineering, molecular manufacturing, etc. are also often applied). Molecular manufacturing will enable the construction of giga-ops computers smaller than a cubic micron; cell repair machines; personal manufacturing and recycling appliances; and much more.

Holographics: Holographics are used for a variety of purposes, whether it be a 3d projection of a location/place, or a conversation with a friend who is miles away. Communication in overdark is usually visual and holographic. Having phone-like devices implanted in their hands. By simply placing your hand against a piece of glass or other clear or see through material you can have a face to face conversation with another person.
